  • Electronic device with invisible light touch panel
    Patent number: 8847921
    Abstract: An electronic device with an invisible light touch panel is disclosed in the present invention. The electronic device includes a circuit board, a visible light source, a light guiding plate, a panel and a cover. The circuit board includes a plurality of invisible light emitters and receivers. The light guiding plate includes an active area and an inactive area. The invisible light outputted from the invisible light emitter transmits to the invisible light receiver via the active area, and the visible light outputted from the visible light source can transmit to the inactive area. The cover is disposed above the light guiding plate. A hole is formed on a surface of the cover, and a position of the hole corresponds to the inactive area on the light guiding plate, so the visible light outputted from the visible light source passes through the cover via the inactive area and the hole.
